FRUIT-PRESS.

and useful Improvements in Fruit-Presses;

and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to that class of presses designed primarily forextracting juice from numerous kinds of fruit although it is to beunderstood that it could well be used for other purposes.

The principal object of the invention is to provide a press having novelmeans for feeding the fruit between a pair of pressing rolls, saidfeeding means being carried by one roll and automatically extensible andretractable at proper intervals for withdrawing the crushed fruit from asupport and feeding it to the rolls as set forth.

\Vith the foregoing general object in view,

the invention resides in the novel features of construction and uniquecombinations of parts to be hereinafter fully described and claimed, thedescriptive matter being supplemented by the accompanying drawings whichconstitute'a part of this specification and in which:

Figure 1 is a vertical section of the improved press;

toothed: fruit crushing rolls 3, while sup ported by the housing 2 is ahopper 4 for feeding the fruit or the like to said rolls, the outlet 5of-said hopper preferably having a suitable device 6 for controlling theamount of feed and for checking it altogether when desired.

The lower end of the housing 2 is contracted and provided with adownwardly and inwardly inclined support 8 upon which the fruit crushedby the rolls 3 is received, said support being preferably perforated asshown at 9 to permit the juice to drain therethrough into the outletpassage 10 beneath which a suitable receptacle 11 may be placed. Thesupport 8 is in close proximity to alower pressing roll 12 whichcooperates with a similar upper roll 13 to extract all of the uice fromthe crushed fruit. The shafts 14 of the two rolls 12 and 13 are gearedtogether by spur gears 15 of uniform size, and the uppermost of thesegears is driven by a pinion 16 on a transverse drive shaft 17 equippedby preference with a hand wheel 18 whereby it may be rotated. Shaft 17also carries a pinion 19 meshing with a spur gear 20 on the shaft of oneof the rolls 3, and said gear 20 in turn meshes with a gear not shown)on the shaft of the other roll 3.

The two gears are preferably of different sizes in order that one roll 3may be driven at a greater rate of speed than the other to bring theteeth of said rolls into play to exert a grinding action on the fruit,which insures that it be reduced to a plup.

Preferably though not necessarily, the ends of the shafts 14 areprovided with wheels 22, the upper wheels contacting with the lower onesto space the rolls 12 and 13 a predetermined amount to permit the pulpto pass therethrough after the juice has been pressed therefrom. Toprevent injury to the machine in case a stone or the like should be fedinto the same through the hopper 4, the

shaft 14 of roll 12 is yieldable downwardly the rear side of the latteris provided with a scraper 25 contacting yieldably with the periphery ofsaid roll to remove the pulp therefrom after extracting of thejuice, atrough 26 being preferably provided at the lower edge of said scrapertocollect any of said juice which might possibly pass with the pulpbetween the two rolls. Thelo'otto'm of trough 26 and the scraper 25 areshown as provided with perforations 27 through which the juice mentionedmay drain into the passage 10.

The upper roll 13 is providedwith a plurality of longitudinallyextending slits 28 opening through its periphery and normally receivingtherein scraping plates 29 as shown most clearly in Figs. 1 and 4, theouter edges of said platesbeing preferably toothed as indicated at 30.Throughout the greater part of each revolution of the roller 13, theplates 29 are received totally in the slits 28, but at the proper time,said plates are projected to the position shown in Fig. 1 to remove thecrushed fruit from the support 8 and feed it between th two pressing arolls. T 0 permit this operation, the plate 29 are mounted as describedbelow.

Preferably fiat arms, 31 are joined at one end to the ends of thescraping plates 29 and at 32 are pivoted between their ends to the endsof roll 13, the ends of said arms remote from the plates 29 being shapedto form'cams 33 adapted to be struck by projections 34 on the ends ofthe roll 12 as will be clear from Figs. land 3. Bythis means, the plates29 are initially started on their outward movement and they may eitherdrop by gravity or be projected by springs such as those shown at 35.The springs 35 act on opposite sides of the pivots 32 to hold thescrapers 29 either in retracted or projected position as shown clearlyin V Fig. l.

The operation of the improved machine is as follows: The fruit is fedbetween the crushing rolls 3 from the hopper 4 and is reduced to a pulpby these rolls, such pulp falling into-the contracted lower end 7 of thehousing 2 and resting on the support.8.

From the'support, any free juice will drain through the perforations 9into the outlet passage 10. As the rolls 12 and 13 rotate in thedirection of the arrows in Fig. 1,'the projections 34-successively comein contact withthe cams 33 of the scrapers 29 andthe latter are thusprojected sufliciently from the slits 28 to cause them to withdraw thecollected pulp from the support 8 and feed it between'the rolls 13 and14 which extract all ju ce therefrom, this juice being all collected inthe outlet passage 10 andcarried to the receptacle 11, wherea theremaining pulp will'be'discharged over the rear end of said passage.into a suitable container such asthat shown at 11. After the scrapers 29have performed their functions, they are automatically returned to theirnormal positions'within the slits 28 by contact with the lower roll 12.7

By constructing the improved press in the manner shown and described, itwill be highly efiicient and durable regardless of the factthat it is ofcofnparatively simple and inexpensive nature. On account of theseadvantages, the specific construction shown constitutes the preferredform of the machine, but it is to be understood that within the scope ofthe invention as claimed,

numerous minor changes may be made without sacrificing the principaladvantages.

I claim: 1; In a fruit press, the combination of fruit crushing means, apair of pressing rolls below said means, a support for the Y port tocause it to remove the fruit from the latter and feed it between therolls as said rolls rotate. 7 r r 3. In a fruit press, the combinationof a pair of pressing rolls,'a support for the fruit adjacent saidrolls, a projectable and retractable scraper carried by one of saidrolls, and means carried by the other roll for automatically projectingsaid scraper onto said support to cause it to remove the fruit from thelatter and feed it between the two rolls as said rolls rotate. 5 r

V 4;. In a fruitpress, thecombination of upper and lower-"rolls, theupper roll being provided with a longitudinal slit opening through itsperiphery, a fruit support adjacent said rolls, a scraper normally con-"fined in said'slit, arms carrying said scraper and pivoted to the endsof said upper roll,-

and means on the other roll for cooperation V with said arms forswinging them outwardly to project the scraper onto the support, saidscraper then serving to remove the fruit from said support and to feedit between the two rolls. i A i 5. In a fruit press, the combination ofupper and lower rolls, the upper roll being provided with a longitudinal'slit opening through its periphery, a fruit support adacent said rolls,a scraper normally confined in said slit, arms carrying said scraper andpivoted to the ends of said upper roll,

and projections on the lower roll for strikmy hand in the presence oftwo subscribing ing said arms and swinging them outwardly witnesses. toproject the scraper onto the support, said BARNEY C. REYNOLDS.
